That's not "messed up" -- that's a screenshot of a Gentoo website tutorial! They're all in multiple colours like that (example). OK, the text in the shot isn't readable in the low-res PDF but it's just an example of what you'll see on the site. I'm sure Bob Moss can dig up an exact URL for that particular page if you like

I could put up a high-res version of the PDF but it could be over 10 times larger without adding any real info.
